Contract opportunities: NAICS 336611
210 open contract opportunities are listed under NAICS code 336611.
This board is updated daily from SAM.gov’s official extract and covers through the previous day (postings through 2026-08-29). Contracts are free to browse and are not part of member fit-scoring, alerts, or the Tuesday digest — those cover grants. Every notice links its official SAM.gov listing; verify details there before responding. “Open” means the response deadline has not passed, or the notice posted within the last 90 days when no deadline is given.
